This is why, sooner rather than later I believe, we need to come up with a good way to pass device trees in and around, asap. An SPL that contains a device tree for the correct board (and passes along to U-Boot which could in turn pass along to the kernel if it's a full tree) would solve your problem, yes?
Yes, if it can be made to fit. The SPL have to fit within 24KB code+data and we are already at 20KB for the MMC/SD version. Size still unknown for NAND SPL with the MTD driver still in very early stages. Can probably shave off a fair bit by removing console output from the SPL but prefer not to.
It should all be doable, even from MMC/SD, with that size limitation. The only issue might be that we would want to use a small initial device tree and merge or replace with a full tree we read off of MMC/SD (or NAND or whatever).
